Obviousness

I am sorry, but there seems to be a significant discrepancy in the patent number provided and the content associated with it.

The initial patent summary identifies EP2449782B1 as "METHOD AND DEVICE FOR PRODUCING A PLASTIC CONTAINER" with assignee KHS CORPOPLAST GMBH, inventors GRABBE, DIRK; KUEHBAUCH, ERIK, and an abstract related to tempering a neck region of a preform for plastic bottle production.

However, the "Litigation summary" and "Derivative works" sections repeatedly refer to EP2449782B1 as a patent concerning "Methods and apparatus for signaling intra prediction for large blocks for video encoders and decoders" (which is the actual title from the Google Patents link provided in the initial prompt) and describe a "Twist-Lock Mechanism for a Hearing Aid" respectively. The content of the "Derivative works" section is entirely focused on a twist-lock mechanism for a hearing aid filter, which completely contradicts the plastic container production method in the patent summary.

Given this fundamental contradiction, I cannot proceed with an obviousness analysis under 35 U.S.C. § 103 for "US patent EP2449782B1" as requested, because the subject matter of the patent is unclear and inconsistently described across the provided sections. To perform a meaningful analysis, the correct patent and its consistent technical details need to be established.

Therefore, I cannot identify combinations of prior art references or explain the motivation for combining them when the core subject of the patent is ambiguous.
